TECHNICAL FIELD

The present invention relates to neuromuscular aid for alleviation and prevention of conditions including muscle cramps and muscle spasms.

BACKGROUND

Muscle cramps, or the involuntary contraction of muscles lasting seconds or minutes, are common. Exercise-associated muscle cramps (EAMC) are painful, and usually necessitate the subject (e.g., athlete) to cease the motions that initiated the cramps. For professional athletes, muscles cramps can have devastating and costly consequences, but most people who have cramps describe the experience as painful and would prefer the cramp be alleviated quickly or prevented altogether. Muscle cramps that occur during sleep lead to poor sleep (quality) and sleep deprivation (quantity) and therefore contribute to excessive daytime somnolence. Muscles cramps also commonly occur in association with systemic diseases or conditions or treatments for these diseases. A partial list of these includes lower motor neuron disease, upper motor neuron disease, post-poliomyelitis, uremia, cirrhosis, hypothyroidism, pregnancy, diarrhea, and hemodialysis. Because muscle cramps are ubiquitous, cause pain and suffering, cause sleep disturbance, and impair athletic performance, rapid and reliable treatment and prevention are needed.

SUMMARY

DETAILED DESCRIPTION

Two simultaneous events are believed to contribute to muscle cramping. First, neuromuscular fatigue leads to a susceptibility for a muscle group to cramp. The cramping is caused by massive neurostimulation of the muscle, originating in the spinal cord, which prolongs painful muscle contraction. Second, the simultaneous inhibition of the opposing muscle group allows the cramp to be sustained. Under normal circumstances, a massive muscle contraction should cause Golgi receptors in the opposing muscle group to fire; however, in the case of muscle cramps, the neuromuscular unit in the opposing muscle is inhibited. Thus, muscle cramps can be understood as occurring at the junction of a nerve and a muscle.

As described herein, a neuromuscular aid is used to stimulate the neuromuscular unit being inhibited in the cramping process to reliably and quickly alleviate the cramp. The neuromuscular aid provides a food grade acid in a concentration between 0.1 wt % and 15 wt % (e.g., 1 wt % to 15 wt %, 1 wt % to 10 wt %, 2 wt % to 8 wt %, 3 wt % to 6 wt %, or 4 wt % to 5 wt %) to the oral cavity of a user. Suitable food grade acids include acetic acid, citric acid, sulfuric acid, lactic acid, and the like. In some embodiments, a neuromuscular aid includes one or more additives such as vitamins, electrolytes, sweetener, coloring agents, preservatives, thickening agents, flavorings, and the like. Suitable vitamins include water-soluble vitamins such as B vitamins (e.g., riboflavin (B₁), thiamin (B₂), niacin (B₃), vitamin B₆, vitamin B₁₂, folic acid, pantothenic acid, and biotin) and vitamin C. Suitable electrolytes include potassium, calcium, and sodium. In some cases, electrolytes are present in a total amount of up to 1 wt %. In certain cases, each of one or more electrolytes is present in an amount of 0.01 wt % to 0.5 wt %. Suitable thickening agents include polysaccharides (e.g., starches, vegetable gums, and pectin) and proteins (e.g., collagen, egg whites, and gelatin). Suitable flavorings include natural and artificial lemon, orange, cinnamon, ginger, berry, and mint flavoring. A pH of the neuromuscular aid may be in a range of 2 to 6 or 3 to 5 or may be selected to create a pH of 2 to 6 or 3 to 5 in the oral cavity of a subject. The neuromuscular aid may be free of sodium (e.g., free of added sodium).

A neuromuscular aid may be in the form of a gas, liquid, carbonated liquid, solid, gum, candy, thin film, gel, spray, suspension, colloid, or aerosol, such that a concentration of the food grade acid in the oral cavity is 1 wt % to 15 wt % upon administration or over time. In one example, a solid candy includes sugar, corn syrup, water, and a food grade acid that is released over time to yield food grade acid in a concentration of 1 wt % to 15 wt % when combined with saliva in the oral cavity of a subject. In another example, a gum includes gum base, sweetener, flavoring, coloring, and food grade acid that is released over time to yield food grade acid in a concentration of 1 wt % to 15 wt % when combined with saliva in the oral cavity of a subject.

In one embodiment, the neuromuscular aid is an aerosol that is pumped or sprayed into the oral cavity of a subject. The neuromuscular aid may be held, swished, or gargled for a length of time (e.g., 60 seconds) and then expelled from the oral cavity. In one example, an aerosol neuromuscular aid includes 10 wt % acetic acid and, when mixed with saliva in the oral cavity of a subject, yields a solution of about 6 wt % acetic acid. In another example, an aerosol neuromuscular aid is an aqueous solution including 15 wt % citric acid and orange flavoring.

In one embodiment, the neuromuscular aid is an oral rinse. The oral rinse is typically an aqueous composition including 1 wt % and 15 wt % (e.g., 1 wt % to 10 wt %, 2 wt % to 8 wt %, 3 wt % to 6 wt %, or 4 wt % to 5 wt %) of food grade acid. The oral rinse may be an aqueous solution. In one example, an oral rinse includes 3 wt % to 6 wt % of acetic acid. In another example, an oral rinse includes 3 wt % to 6 wt % of acetic acid and citric acid. An oral rinse may include one or more additives such as vitamins, minerals, sweetener, coloring agents, preservatives, thickening agents, flavorings, and the like as described herein. A pH of the neuromuscular aid may be in a range of 2 to 6 or 3 to 5 or may be selected to create a pH of 2 to 6 or 3 to 5 in the oral cavity of a subject.

A neuromuscular aid may be administered to the oral cavity of a subject suffering from muscle cramps. In some cases, the neuromuscular aid is administered to the oral cavity of a subject for the prevention of muscle cramps. The neuromuscular aid is held in the oral cavity of the subject for a length of time such that all or most of the oral cavity and tongue are in contact with the oral rinse. Holding the neuromuscular aid in the oral cavity may include at least one of swishing the neuromuscular aid in the oral cavity and gargling with the neuromuscular aid. In some cases, the neuromuscular aid is expelled from the oral cavity after the neuromuscular aid is held in the oral cavity for the length of time. If desired, the neuromuscular aid may be ingested after being held in the oral cavity for the length of time.

Continuous and repeated stimulation of the nerves by a neuromuscular aid held in the oral cavity for a length of time, rather than incidental contact when being swallowed, creates a biological change or response to targeted anatomy more quickly, fully, and efficiently and less invasively than swallowing the neuromuscular aid. While being held in the oral cavity, the nerves that control a range of involuntary responses are stimulated, causing relief of maladies such as cramping.

Swishing, holding, or gargling a neuromuscular aid in the mouth, as opposed to swallowing, allows subjects with a delicate gag reflex, sensitive digestive tract, or sore throat to avoid ingestion of the neuromuscular aid while still benefiting from it. This is especially important for subjects whose digestive systems have been compromised by therapies such as chemotherapy.

Certain chemicals take longer than others to stimulate chemoreceptors. Substances such as acids, drugs, vitamins, or other medicinal solutions that are held, swished, or gargled in the oral cavity, rather than ingested, create a biological response that may be manifested more quickly. These biological changes may be effected in systems of the subject including, but not limited to, the nervous system, the endocrine system, the digestive system, the urinary system, the respiratory system, the circulatory system, the lymphatic system, the immune system, the reproductive system, the muscular system, the skeletal system, and the integumentary system. These systems may all be affected simultaneously or individually depending on the application, subject, and formulation.

A neuromuscular aid is typically held in the oral cavity for 5 seconds to 120 seconds (e.g., 10 seconds to 60 seconds, up to 20 seconds, up to 40 seconds, or up to 60 seconds), or for a length of time required to alleviate cramping symptoms. The frequency of use and length of time held in the oral cavity may be adjusted depending on the subject, location of cramp, application, and formulation of the neuromuscular aid. In one example, a shorter length of time may be required for a child to experience relief of symptoms than an adult male. In another example, a longer length of time may be required for a cramp in a foot than a cramp in the neck. Typically, a neuromuscular aid having a higher concentration requires a shorter length of time than a neuromuscular aid having a lower concentration.

Holding the neuromuscular aid in the oral cavity stimulates receptors on the tongue, posterior pharynx, and other surfaces in the mouth, as well as receptors throughout the gastrointestinal tract. FIG. 1 depicts a lateral view of a human oral cavity 100 and associated nerves, including the chorda tympani nerve 102, trigeminal ganglion 104, facial nerve 106, superior laryngeal nerve 108, vagus nerve 110, and glossopharyngeal nerve 112. The brain stem 114 and solitary tract nucleus 116 are also depicted. The stimulation of these receptors leads to a neuronal discharge from the spinal cord to the opposing muscle group, thus allowing the cramping muscle to stretch and cease cramping. In some cases, a neuromuscular aid may inhibit spinal cord neuronal impulses that initiate and maintain muscle cramping.

As described herein, a neuromuscular aid relieves, alleviates, ameliorates, and/or prevents muscle cramps, including cramps that occur, for example, during exertion, resting, night time, and menstruation, and may promote relief of generalized pain from muscle spasms and muscle fatigue, headaches associated with muscle tension and generalized pain associated with premenstrual syndrome, fibromyalgia, and treatments and systemic diseases or that cause muscular aches or pains. The neuromuscular aid stimulates the neuromuscular unit being inhibited in the cramping process, thereby reliably and quickly alleviating the cramp.

Testing has shown that swishing a neuromuscular aid that stimulates the nerves, chemoreceptors, and/or taste buds in the mouth typically brings about faster biological responses or changes to certain anatomy than swallowing the same substance. For example, the effectiveness of swishing a neuromuscular aid in the mouth and expelling the solution after 60 seconds has been shown on multiple occasions with multiple test subjects. In the case of cramp relief, subjects have consistently gotten relief from muscle cramps in less than one minute of swishing a neuromuscular aid specifically formulated for swishing, whereas swallowing the same neuromuscular aid brought similar relief after more than 2 to 5 minutes.

A neuromuscular aid may be packaged to provide multiple doses or a single dose. In one embodiment, a neuromuscular aid in the form of a gas, liquid, carbonated liquid, spray, or aerosol is provided in a single package (e.g., a bottle) that yields at least 10, 20, or 30 doses. In another embodiment, a neuromuscular aid in the form of a liquid, solid, gum, candy, thin film, or gel is packaged as a single dose. Packaging for the neuromuscular aid typically includes instructions for use. In one example, instructions for use of a neuromuscular aid are printed on the exterior of the packaging.

FIG. 2 depicts packet 200 including a neuromuscular aid. As used herein, “packet” generally refers to packaging of any sort designed to contain a quantity of a gas, liquid, solid, gum, candy, thin film, gel, suspension, colloid, aerosol, or the like. Packet 200 may be made of materials including foil, polymer, and paper. Packet 200 may be in the form of a wrapper or sealed packaging. Packet 200 may contain a single dose or multiple doses of a neuromuscular aid. Packet 200 may be opened manually by a user. Packet 200 may be resealable, reusable, disposable, or recyclable.

The neuromuscular aid in packet 200 may be in the form of an oral rinse or a gel. A single dose may include 1 to 50 mL, 3 to 30 mL, or 5 to 10 mL of the neuromuscular aid. Packet 200 includes instructions for use 202. Instructions for use 202 are printed on an exterior of packet 200. When packet 200 includes a neuromuscular aid in the form of an oral rinse, the instructions for use may include instructions to retain the oral rinse in the oral cavity of a subject for a length of time for alleviation or prevention of muscle cramps. In some cases, instructions for use 202 include instructions to expel the oral rinse from the oral cavity after retaining the oral rinse in the oral cavity for a length of time. In other cases, instructions for use 202 include instructions to swallow or ingest the oral rinse after retaining the oral rinse in the oral cavity for a length of time. In certain cases, instructions for use 202 include instructions to gargle with the oral rinse or swish the oral rinse in the oral cavity. In one example, instructions for use 202 include instructions to rinse the oral cavity with the oral rinse for 5 seconds to 120 seconds or up to 60 seconds.
